How can I make a on ENTER\_FRAME function from constantly running?

Here is what I have

```auto

addEventListener(Event.ENTER_FRAME, onEnterFrame);
private function onEnterFrame(event:Event):void
        {
            var speed:Number = 6;
            var ysize:Number = Tall - this.height;
            var xsize:Number = Wide - this.width;

            this.height += ysize / speed;
            this.width += xsize / speed;

            if (Math.abs (ysize) < 0.3 && Math.abs (xsize) < 0.3) {
                this.height = Math.abs (ysize);
                this.width = Math.abs (xsize);
                trace("done");
                
            }
        }

```

I know if I used the same thing in AS2 all I needed to do is delete this.onEnterFrame.

Are there pre-defined classes in AS3 that would do the same thing.
